Men with this condition have been shown on testicular biopsy to have adequate spermatogenesis, and are theoretically producing sperm capable of fertilizing an oocyte. Yet epididymal transit was thought to be essential for the maturation of spermatozoa and development of their fertilizing ability since the characteristics of sperm motility improve as the sperm passes through the cauda. However recent studies in man have shown that spermatozoa aspirated from the obstructed caput epididymis and ductuli efferentia are, in fact, capable of fertilization in vitro. Microsurgical epididymal sperm aspiration (MESA) from the proximal region (caput) of the epididymis, obtained 0.5 x 10(6) sperm per ml, following washing and direct swim-up. Twelve oocytes were inseminated and three embryos were generated for transfer. The patient conceived and delivered a healthy female baby weighting 2838 gm, on March 3, 1994. This is the first documentation in Taiwan of live birth resulting from MESA from a patient with CAVD combined with in vitro fertilization and embryo transfer. ------>tmu_sno=None ------>sno=1921 ------>authors2=None ------>authors3=None ------>authors4=None ------>authors5=None ------>authors6=None ------>authors6_c=None ------>authors=Tzeng, C.R., Hsiao, S.Y., Chien, L.W., Chiang, H.S., Wu, C.C., and ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=None ------>publish_area=None ------>updateTitle=Pregnancy following in vitro fertilization and embryo transfer by microsurgical epididymal sperm aspiration from a patient with congenital absence of the vas deferens: a case report. ------>language=2 ------>check_flag= ------>submit_date= ------>country=None ------>no= ------>patent_SDate=None ------>update_bywho= ------>publish_year=1996 ------>submit_flag= ------>publish_month=None |
